Sounds like a strange request but if you check out this thread, you'll see why I want this. The tl;dr version is this: I get migraine headaches. The green colored light has been scientifically proven to ease migraine pain. I want everything on my screen to be green. Yes, everything.

And the strange thing is that it worked on my Dell Inspiron 13 7378, as you'll see if you click the link above. I try the exact same thing with my Alienware and nothing happens.

Can some of you put your thinking caps on and help me troubleshoot this problem?

Thank you

NOTE: If you click that link, you'll see I gave the info for my Alienware. It's because I created that post with the Alienware. The next time I got online I was using my Dell. I only just got around to trying it on my Alienware last night (because I had a migraine headache).
